Hi R users:

I try this code, where "fun" is a parameter of a random generating function name, and I pretend to use "..." parameter to pass the parameters of different random generating functions.

What am I doing wrong?

f1<-function(nsim=20,n=10,fun=rnorm,...){

    vp<-replicate(nsim,t.test(fun(n,...),fun(n,...))$p.value)     return(vp)
}

This works!
f1()
f1(n=20,mean=10)

This two fails:
f1(n=10,fun=rexp)
f1(n=10,fun=rbeta,shape1=1,shape2=2)

Thank you for your help.

Kenneth
